Ma ogtahay waxa ay ku kala duwan yihiin LCD,LED iyo OLED?
Shaashadda soo-bandhigidda waxa lagu magacaabaa mid ka mid ah hal-abuurradii ugu waaweynaa ee qarnigii 20-aad.
Aad uma badna. Nolosheennu waxay ammaan u tahay muuqaalkeeda.
Kobcinta sayniska iyo tignoolajiyada, shaashaduhu kuma eka oo kaliya isticmaalka shaashadaha TV-ga.
Ganacsi baaxad weynLED waxay soo bandhigtaa shaashadahaBilaw in aan nolosheenna soo dhex galno, sida xarumaha ganacsiga, shineemooyinka, waxaa lagu arki karaa meelo kala duwan sida goobaha isboortiga ee gudaha, waxaana sidoo kale dhegahayaga ku jira LCD, LED, OLED iyo ereyo kale oo xirfad leh, inkastoo ay badan yihiin. dadku way ka hadlaan iyaga, laakiin dadka badankiisu wax yar ayay ka og yihiin.
Haddaba, waa maxay farqiga u dhexeeya Lcd, oled iyo oled?
LCD,BANDHIGYADA LEDiyo OLED
1, LCD
LCD waxay u soo gaaban tahay Bandhiga Liquid Crystal oo Ingiriisi ah.
Waxaa jira inta badan TFT, UFB, TFD, STN iyo noocyo kale. Qaab dhismeedkeeda waxaa ka mid ah kubbadda caagga ah, kubbadda dhalada, xabagta jir, substrate galaaska, polarizer sare, lakabka jihada, crystal dareere, qaabka ITO-ga, barta korantada, korantada IPO iyo polarizer hoose.
Qaadashada shaashada xayeysiiska LCD tusaale ahaan, waxay qaadanaysaa TFT-LCD ee ugu caansan, kaas oo ah muuqaal khafiif ah oo transistor dareere ah. Qaab dhismeedkeeda aasaasiga ah waa in la dhigo sanduuqa crystal dareeraha ah ee laba lakab oo isku mid ah, ku dheji transistor filim khafiif ah (oo ah TFT) muraayadda hoose ee hoose, u deji shaandhada midabka muraayadda hoose ee sare, jihada wareega ee molecules crystal dareeraha waxaa xakameynaya calaamada iyo danabku waxay ku beddelaan transistor-ka filimka khafiifka ah, si loo gaaro ujeedada bandhigga iyadoo la xakameynayo in iftiinka polarized ee pixel kasta uu sii daayo iyo in kale.
Mabda'a soo bandhigida crystal dareere waa in crystal dareere soo bandhigi doonaa sifooyin iftiin kala duwan oo hoos waxqabadka danab kala duwan. Shaashadda muraayadda dareeraha ah waxay ka kooban tahay habab badan oo dareere ah. Shaashada muraayadda muraayadda dareeraha ah ee monochrome, crystal dareere waa pixel (cutubka ugu yar ee lagu soo bandhigi karo shaashadda kumbuyuutarka), shaashadda muraayadda dareeraha dareeraha ah, pixel kasta wuxuu ka kooban yahay crystals dareere ah casaan, cagaar iyo buluug. Isla mar ahaantaana, waxaa loo tixgelin karaa in ay jirto diiwaan 8-bit ah oo ka dambeeya kiristaalo kasta oo dareere ah, iyo qiimaha diiwaanka ayaa go'aaminaya dhalaalka mid kasta oo ka mid ah saddexda unug ee dareeraha ah, si kastaba ha ahaatee, qiimaha diiwaanku si toos ah uma hayo. wad dhalaalka saddexda unug ee crystal dareeraha ah, laakiin waxa laga galaa “palette. Waa wax aan macquul ahayn in pixel kasta lagu qalabeeyo diiwaanka jireed. Dhab ahaantii, hal xariiq oo diiwaanka ayaa qalabaysan. Diiwaanadani waxay ku xidhan yihiin xariiq kasta oo pixels ah markoodana lagu shubaa waxa ku jira xariiqan, wada dhammaan xadhkaha pixel si ay u muujiyaan sawir dhamaystiran.
LED-ku waa u gaaban yahay Diode Light Emitting. Waa nooc ka mid ah diode semiconductor, kaas oo tamarta korontada u beddeli kara tamarta iftiinka.
Marka elektaroonnada lagu daro godad, iftiin muuqda ayaa soo bixi kara, sidaas darteed waxaa loo isticmaali karaa in la sameeyo diodes iftiin leh. Si la mid ah diodhyada caadiga ah, diodhyada iftiimiya iftiinka waxay ka kooban yihiin isgoysyada pn waxayna sidoo kale leeyihiin dhaqdhaqaaq aan jiho lahayn.
Mabda'eeda marka danabka togan lagu daro diode-ka iftiimaya, godadka lagu duray aagga N ee ka soo jeeda aagga P iyo electrons lagu duro aagga P ee aagga N, gudaha dhowr microns oo u dhow isgoyska PN, waa la isku daray. leh electrons ee gobolka N iyo godadka gobolka P siday u kala horreeyaan si ay u dhaliyaan fluorescence iskiis ah.
Xaaladaha tamarta ee electrons iyo godadka qalabka semiconductor ee kala duwan ayaa kala duwan. Marka electrons iyo godadku isku daraan, tirada tamarta la sii daayo way kala duwan tahay. Tamar badan oo la sii daayo, waa la gaabanayaa hirarka hirarka iftiinka soo baxaya. Sida caadiga ah loo isticmaalo waa diodes ka bixiya iftiin cas, iftiin cagaaran ama huruud ah.
LED waxaa loo yaqaan 'Isha Iftiinka Jiilka Afraad', kaas oo leh astaamaha badbaadinta tamarta, ilaalinta deegaanka, badbaadada, nolosha adeeg dheer, isticmaalka tamarta yar, kulayl yar, dhalaalka sare, biyuhu, yar yar, aan shoogga lahayn, khafiifinta fudud, iftiinka xoogga leh, dayactir fudud , iwm, waxaa si weyn loogu isticmaali karaa meelo kala duwan sida tilmaanta,Muujinta LED, qurxinta, iftiinka dambe, iftiinka guud, iwm.
Tusaale ahaan, muraayadda soo-bandhigidda LED-ka, Shaashadda LED-ka ee Xayeysiiska, Laydhka signalka gaadiidka, nalka baabuurta, nalka dambe ee LCD, nalka guriga iyo ilo kale oo iftiin ah.
3, OLED
OLED waa u gaaban Organic Light-Emitting Diode. Waxa kale oo loo yaqaan bandhig laser koronto oo dabiici ah, semiconductor iftiiminaya nalka organic.
Diode-kan waxa laga helay shaybaadhka sannadkii 1979kii oo uu sameeyay borofisar Shiine ah oo Maraykan ah Deng Qingyun.
OLED waxay ka kooban tahay unugga bandhiga OLED ee dibadda ah iyo walxaha iftiiminaya iftiinka oo ku dheggan, oo ay ku jiraan cathode, lakabka sii daynta, lakabka korantada, anode iyo saldhigga. Cutub kasta oo soo bandhiga OLED wuxuu xakameyn karaa inuu soo saaro iftiinka saddex midab oo kala duwan.
Tiknoolajiyada soo bandhigida OLED waxay leedahay sifada is iftiiminta, iyadoo la isticmaalayo daahan walxo dabiici ah oo dhuuban iyo substrate dhalada ah. Marka uu jiro wareegga korantada, walxahan dabiiciga ah waxay soo saari doonaan iftiin, iyo xagasha muuqaalka ee shaashadda OLED waa mid weyn, waxayna badbaadin kartaa isticmaalka tamarta. Tan iyo 2003, tignoolajiyadan soo bandhigida ayaa lagu dabaqay ciyaartoyda muusiga MP3.
Maalmahan, wakiilka caanka ah ee codsiga OLED waa shaashadda taleefanka gacanta. Shaashadda OLED waxay muujin kartaa isbarbardhigga sawirka qumman, sawirka bandhiguna wuxuu noqon doonaa mid muuqda oo dhab ah. Sababo la xiriira sifooyinka kristanta dareeraha ah, shaashadda LCD ma taageerto foorarsiga. Taas bedelkeeda, OLED waxaa laga dhigi karaa shaashad qaloocan.
Farqiga Saddexda
1, On gamut midabka
Shaashadda OLED waxay soo bandhigi kartaa midabyo aan dhammaad lahayn mana saameeyaan nalka dambe, laakiin Shaashadda LED oo leh dhalaal wanaagsan iyo xagal daawasho.
Pixels waxay leeyihiin faa'iidooyin weyn marka la soo bandhigo dhammaan sawirada madow, wakhtigan, midabka midabka ee shaashadda LCD wuxuu u dhexeeyaa 72 iyo 92 boqolkiiba, halka kan muraayadda uu ka sarreeyo 118 boqolkiiba.
2, Xagga qiimaha
Shaashadaha LED-ka ee cabbirka la mid ah ayaa laba jeer ka qaalisan kuwa LCD-ga ee ku jira gidaarka muuqaalka ee pixel pitch ee yar yar, halka muraayadaha OLED ay aad qaali u yihiin.
3, Marka la eego tignoolajiyada bislaaday ee dhalaalka iyo bilaa-xadhkaha.
Shaashadda LED aad ayey uga fiican tahay shaashadda LCD iyo OLED ee dhalaal iyo aan kala go 'lahayn, gaar ahaan cabbirka weyn ee gidaarka muuqaalka ah ee loogu talagalay shaashadda xayeysiinta ama isticmaalka calaamadaha dhijitaalka ah ee ganacsiga gudaha.
Halka LCD ama OLED loogu talagalay gidaarka fiidiyowga dhijitaalka ah ee cabbirka weyn ee u baahan kala qaybsanaan, farqiga u dhexeeya muraayadaha ayaa saameyn doona waxqabadka iyo dareenka daawadayaasha.
4, Dhanka waxqabadka muuqaalka iyo xagasha bandhiga
Muujinta gaarka ah ayaa ah in xagasha muuqaalka ah ee shaashadda LCD ay aad u yar tahay, halka muraayadda LED ay ku qanacsan tahay lakabyada iyo waxqabadka firfircoon ee horumarinta tignoolajiyada ee muujinta hogaaminta, marka lagu daro, qoto dheer ee shaashadda LED ayaa si fiican ugu filan gaar ahaanYONWAYTECH dhuuban pixel pitch xalka bandhiga hogaaminta.
